Closed-loop current sensor MA130

clampthree-phase

Advantages - Flexible three-phase current sensors - Battery life: 500 hours - Measurements from 0.5 A to 3 kA - IP67, 600 V CAT IV Description The MiniFlex® MA130 is a flexible current sensor comprising 3 measurement loops. It can be connected directly to a power analyser, logger, etc., to measure 3-phase currents or to perform up to 3 independent current measurements. These flexible coils offer the following major advantages: • Current measurement even in places where access is difficult • Large measurement range • Bandwidth suitable for industrial frequencies and harmonic analysis • No saturation effect, so no overheating • Constant low phase shift appropriate for wattmetric measurements Main specifications: • Measurement range: 0.5 A to 3 kA • 3 calibres • Sensor length (clamping Ø): 25 cm (Ø 7 cm) • Ingress protection of sensor/processing unit: IP67 / IP54 • Output signal: AC voltage • Output via 3 coaxial cables terminated by isolated BNC safety plugs • Power supply: 2 x 1.5V AA batteries or external µUSB type B 5V • Battery life: 500 hours • 600 V CAT IV
